Kit of parts (only, use with PCB and your 8-12 volt unregulated supply) for the +5 volt regulator option. If your motor supply is more than +12V, or if you are running more than one axis driver, you should probably add a heatsink (it doesn''t take a big one) as the LM317 may get hot and shut down. If your only source of power is more than 12 volts, you can augment this kit by replacing the LM317 with a switching regulator like the Murata OKI-78SR-5/1.5-W36-C which can take up to 36 volts and still provide 1.5 amps at 5volts.
